Scale
Beef and Coating
- 1 1/2 pounds Flank Steak
- 1/4 cups Cornstarch
Sauce and Seasonings
- 2 tablespoons Sesame Oil
- 1/2 teaspoon Minced Garlic Cloves
- 1/2 cups Soy Sauce
- 1/2 cup Beef Broth
- 3/4 cups Brown Sugar
- 1/4 cup Onion, chopped
- 1/4 teaspoon Red Pepper Flakes
Garnish
- Sesame Seeds
- Green Onions
Instructions
- Prepare the Beef: Cut the flank steak into thin strips. Place the strips into a ziplock bag, add the cornstarch, and shake the bag to thoroughly coat the beef evenly.
- Combine Sauce Ingredients: In the slow cooker, pour in the sesame oil, minced garlic, soy sauce, beef broth, brown sugar, chopped onion, and red pepper flakes. Stir these ingredients together to create the sauce base.
- Add Beef to Slow Cooker: Add the cornstarch-coated flank steak strips to the sauce in the slow cooker. Stir gently to ensure the beef is fully coated with the sauce mixture.
- Cook the Beef: Cover and cook on high for 2 to 3 hours, or on low for 4 to 5 hours, until the beef is cooked through and tender.
- Serve and Garnish: Serve the Korean beef over cooked rice. Garnish with sesame seeds and chopped green onions to add texture and a fresh finish.
Notes
- For a thicker sauce, you can remove the lid during the last 30 minutes of cooking to allow it to reduce slightly.
- Using thin strips of flank steak helps the meat cook evenly and become tender in the slow cooker.
- This recipe can be doubled easily for larger groups; cooking times may remain the same.
- Leftovers store well in the refrigerator for up to 3 days and can be reheated on the stovetop or microwave.
